Description

Technical Field

[0001] This utility model relates to the field of aeration technology, and in particular to an aeration device for wastewater treatment. Background Technology

[0002] Aeration devices are core equipment in wastewater treatment, primarily used to oxygenate sewage, promote the degradation of organic matter by aerobic microorganisms, and simultaneously agitate the water to prevent sludge sedimentation. Their core function is to improve oxygen transfer efficiency, ensuring efficient biochemical reactions. The selection of an aeration device requires comprehensive consideration of water quality, treatment scale, energy consumption, and maintenance costs. High-efficiency aeration technologies (such as micro-nano bubbles and intelligent aeration control) are becoming a development trend to reduce energy consumption and improve treatment efficiency. This equipment is widely used in municipal wastewater, industrial wastewater, and aquaculture, and is a key component of processes such as activated sludge and biofilm processes.

[0003] Existing aeration devices for wastewater treatment have the following main drawbacks: Inconvenient replacement and maintenance: Aeration pipes are usually fixed to the bottom of the aeration tank with clamps. When replacing aeration discs, the water in the tank must be drained, which is not only cumbersome to operate, but also increases maintenance costs and time; Limited aeration range: The aeration pipes are fixed to the bottom of the tank, resulting in a narrow distribution range of bubbles and low oxygen transfer efficiency. Especially in large-scale aeration tanks, dead zones are easily formed, which affects the degradation effect of microorganisms on organic matter and restricts the improvement of overall treatment efficiency. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aeration device for wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aeration device for wastewater treatment, comprising a guide rail and a main pipe, wherein multiple vertical pipes are fixed at equal intervals on the surface of the main pipe, and a sleeve is rotatably connected to the surface of each vertical pipe via a sealed bearing, an aeration pipe is fixed at the top of the sleeve, multiple aeration discs are fixed at equal intervals on the upper surface of the aeration pipe, and air nozzles are provided at both ends of the aeration pipe, a sliding groove is provided on the side wall of the guide rail, and a slider is slidably connected inside the sliding groove, a detachable retainer is fixed on the surface of the slider, the end of the main pipe near the guide rail is fixedly connected to the retainer, and a lead screw is rotatably connected inside the sliding groove via a bearing, the lead screw passing through the slider and being rotatably connected to the slider via a thread.

[0006] Furthermore, a flexible hose is fixed to one end of the main pipe near the guide rail, and the flexible hose is connected to the air supply device.

[0007] Furthermore, the top wall of the aeration pipe is provided with multiple internally threaded connectors at equal intervals, and the bottom of the aeration disc is connected to the internally threaded connectors by threads.

[0008] Furthermore, the air nozzles at both ends of the aeration pipe are arranged in opposite directions.

[0009] Furthermore, a geared motor is fixed to the top of the guide rail, and the top of the lead screw is fixedly connected to the output end of the geared motor.

[0010] Furthermore, a guide rod is fixed inside the groove, and the guide rod passes through the slider and is slidably connected to the slider.

[0011] Furthermore, the upper surface of the slider is provided with a groove, and a spring is fixed to the bottom wall of the groove. A locking rod is fixed to the top of the spring, and the locking rod is slidably connected to the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model is an aeration device for wastewater treatment, which includes a main pipe, a vertical pipe, a sleeve, an aeration pipe, an internally threaded connector, an aeration disc, a jet nozzle, and a hose. The aeration pipe is rotatably connected to the surface of the vertical pipe through the sleeve. Air enters the main pipe and then enters the aeration pipe through the vertical pipe. Finally, aeration is achieved by the aeration disc. During this process, the air in the aeration pipe is also ejected from the jet nozzles on both sides. Under the counter-propulsion force, the aeration pipe rotates on the surface of the vertical pipe through the sleeve, thereby driving the aeration disc to rotate, increasing the aeration range and enhancing the aeration effect.

The main pipe is fixedly connected to the clamping sleeve, and the clamping sleeve is fixedly fitted onto the surface of the slider. When it is necessary to replace the aeration disc, the reduction motor is started to drive the lead screw to rotate. The lead screw will drive the slider to slide upward along the groove of the guide rail, thereby raising the bottom of the main pipe aeration tank. Therefore, it is not necessary to drain the water in the aeration tank before replacement, which improves the portability of replacement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, an aeration device for wastewater treatment is disclosed, comprising a guide rail 1 and a main pipe 2. Multiple vertical pipes 3 are fixed at equal intervals on the surface of the main pipe 2. Each vertical pipe 3 is rotatably connected to a sleeve 4 via a sealed bearing. An aeration pipe 5 is fixed at the top of the sleeve 4. Multiple aeration discs 7 are fixed at equal intervals on the upper surface of the aeration pipe 5. Air nozzles 8 are provided at both ends of the aeration pipe 5. A sliding groove 10 is provided on the side wall of the guide rail 1, and a slider 11 is slidably connected inside the sliding groove 10. A detachable retainer 15 is fixed on the surface of the slider 11. The end of the main pipe 2 near the guide rail 1 is fixedly connected to the retainer 15. A lead screw 18 is rotatably connected inside the sliding groove 10 via a bearing. The lead screw 18 passes through the slider 11 and is rotatably connected to the slider 11 via a thread.

[0023] A hose 9 is fixed to one end of the main pipe 2 near the guide rail 1, and the hose 9 is connected to the air supply device.

[0024] In this embodiment, the air supply device of the aeration device is the same as that of the prior art. When oxygen is supplied by the air supply device, the oxygen enters the main pipe 2 from the hose 9, then enters the multiple aeration pipes 5 from the multiple vertical pipes 3 respectively, and finally sprays out from the multiple aeration discs 7 at the top of the aeration pipes 5.

[0025] Multiple internal threaded connectors 6 are evenly spaced on the top wall of the aeration pipe 5, and the bottom of the aeration disc 7 is connected to the internal threaded connectors 6 by threads.

[0026] The installation method of the aeration disc 7 is the same as that of the existing technology. It is fixedly connected to the aeration pipe 5 by screwing in the internal thread connector 6. When the aeration disc 7 needs to be replaced, it can be unscrewed from the internal thread connector 6.

[0027] The air nozzles 8 at both ends of the aeration pipe 5 are arranged in opposite directions.

[0028] In addition to being discharged from the aeration disc 7, the oxygen entering the aeration pipe 5 is also sprayed out from the two jet nozzles 8. Since the two jet nozzles 8 are in opposite directions, under the reverse thrust, they will push the aeration pipe 5 and the sleeve 4 to rotate on the surface of the vertical pipe 3, thereby causing the aeration disc 7 to rotate as well, thus increasing the aeration range.

[0029] A geared motor 19 is fixed at the top of the guide rail 1, and the top of the lead screw 18 is fixedly connected to the output end of the geared motor 19.

[0030] The guide rail 1 is fixed to the inner wall of the aeration tank by bolts and is installed vertically. The reduction motor 19 is located at the top of the aeration tank. After the reduction motor 19 is started to rotate forward or in reverse, the reduction motor 19 drives the lead screw 18 to rotate. The lead screw 18 drives the slider 11 to slide along the slide groove 10, thereby using the slider 11 to drive the sleeve 15 and the main pipe 2 to move, realizing the lifting and lowering of the main pipe 2 in the aeration tank. When it is necessary to replace the aeration disc 7, the main pipe 2 can be raised from inside the aeration tank to replace the aeration disc 7 on the water surface without draining the water in the aeration tank.

[0031] A guide rod 17 is fixed inside the slide groove 10. The guide rod 17 passes through the slider 11 and is slidably connected to the slider 11.

[0032] When the lead screw 18 drives the slider 11 to move, the guide rod 17 can play a guiding role, and the guide rod 17 can bear the shearing force of the main pipe 2 on the slider 11, thereby preventing the lead screw 18 from deforming.

[0033] The upper surface of the slider 11 has a groove 12, and a spring 13 is fixed to the bottom wall of the groove 12. A locking rod 14 is fixed to the top of the spring 13. The locking rod 14 is slidably connected to the groove 12. The top wall of the sleeve 15 has a locking hole 16, and the top of the locking rod 14 is inserted into the locking hole 16.

[0034] When disassembling the main pipe 2 to replace the aeration disc 7, press down on the retaining rod 14 to retract it into the groove 12. The retaining rod 14 will disengage from the retaining hole 16. Then, remove the retaining sleeve 15 from the surface of the slider 11. After replacing the aeration disc 7, similarly, press the retaining rod 14 first and then put the retaining sleeve 15 onto the surface of the slider 11. The spring 13 will push the retaining rod 14 out of the groove 12 and into the retaining hole 16, thus fixing the retaining sleeve 15 to the surface of the slider 11. Since the retaining sleeve 15 is fitted onto the surface of the slider 11, the engagement between the two bears the weight of the main pipe 2. The retaining sleeve 15 and the slider 11 are fixed by the spring 13 and the retaining rod 14. The retaining rod 14 and the spring 13 do not bear torque, thus achieving a firm connection.

[0035] Working principle: The guide rail 1 is fixed to the inner wall of the aeration tank with bolts. The hose 9 is connected to the air supply component. In use, the reduction motor 19 is started, which drives the slider 11 and the main pipe 2 to sink to the bottom of the tank. Oxygen enters the main pipe 2 from the hose 9, and then enters the multiple aeration pipes 5 from the multiple vertical pipes 3. Finally, it is sprayed out from the multiple aeration discs 7 at the top of the aeration pipes 5. In addition to being discharged from the aeration discs 7, oxygen is also sprayed out from the two jet nozzles 8. Since the two jet nozzles 8 are in opposite directions, under the counter-propulsion force, they will push the aeration pipes 5 and the sleeves 4 to rotate on the surface of the vertical pipes 3, thereby causing the aeration discs 7 to rotate as well, thus increasing the aeration range.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
